Worth the price

for the price and the features it is more than worth it plus it is user friendly.

FYI

Pros: this is a decent alarm, I’m using it in a basic configuration because I don’t have no power locks / windows etc. It also has a pretty good (unobstructed line of site) range of about 2 to 2.5block radius.
The remote seems to work great to. The Remote start works great, it usually starts my car in the 1st attempt. It doesn’t hold the starter on too long either, just enough to get it started (with out causing any damage)

Cons: this is not the cheapest unit, it only came with one transmitter, reasonable priced replacement transmitters are hard to find (when they 1st came out). DEI wants so much for a replacement 2 way transmitter. That it’s the same price as buying the alarm all over again from this site. The remote doesn’t have a quick one touch button for back light or vibrate mode. And the 2 way transmitter that sounds when you’re car is going off isn’t loud. It’s just beeps, when another brand I was using had a loud baby siren sound

Clifford Rsx3.5 Alarm System

This system i just order because my friend have one. It very easy to use and installation is a breeze if you bring it to a shop. The range of the response lcd is awesome. That the reason why i baught one. This is one of the best alarm in the market and don't take my word for it, try it yourself.
